Ubel from Frieren: Beyond Journey's End
Keep in mind that settings may vary slightly between different versions. See below for more details.
When I tested this with different checkpoints and LoRAs, it seemed to work quite well.
Pony:
A LoRA weight of 0.8 works great, though you can adjust the strength as you prefer.
Prompts I usually used:
dark green hair, side ponytail, purple eyes, black dress, sleeveless, black choker, armlet, halter dress, short dress, belt, straps, black glove, single glove
